<pre>Buiding the RISC-V Linux kernel w/ Clang, we hit this error, ex:
```
.altmacro
.macro foo
LOCAL bar
bar:
jmp bar
.endm
foo
```
<instantiation>:1:1: error: invalid instruction mnemonic 'local'
We can work around this via local labels, ie:
```
.macro foo
1:
jmp 1b
.endm
foo
```
<a href="https://sourceware.org/binutils/docs/as/Macro.html#Macro">https://sourceware.org/binutils/docs/as/Macro.html#Macro</a> documents `LOCAL`:
Warning: LOCAL is only available if you select “alternate macro syntax” with
‘--alternate’ or .altmacro. See .altmacro.
